When Clare Vivier was looking for the perfect leopard for fall, she rang her good friend Melissa Coker of Wren. "She'd been working to source something and was finding it terribly challenging to find something of great quality," Coker said. "We used a really amazing faux leopard in fall that we sourced over a couple of years from Europe. It's amazing, it even has cowlicks like a real animal."

Instead of heading to Europe to buy her own run of fabric, Vivier and Coker decided to collaborate. The latter provided remnants from her fall collection and Vivier turned them into bags—a great, everyday tote ($290) and a perfectly sized clutch ($200). In true collaborative spirit, it was something new for both of them. "[Clare] developed totally new silhouettes that are different from anything she'd done in the past, but still retain the Vivier aesthetic," Coker said. The bags will be available on their respective sites in August and then Satine, in LA, soon after.

Aside from the environmental benefits of collaborating—"Typically, there is very little that can be done with these scraps of fabric. We've made contrast pockets out of them, or used pieces for different types of trimming," Coker said. "Really though, it's very challenging to find any use for them other then bin liner. If you think about all the clothes that are produced in our country on a daily basis, you can imagine what sort of waste these remnants turn into."—it's just plain old fun. Coker's already set her sights on another friendly partnership: "Dana Lorenz and I have been talking about a jewelry collaboration for Fallon that I think would be really great to work on."
